This PR adds pylint to the build pipeline. The builds will only fail if pylint identifies fatal errors. A full pylint run will also happen, but currently it will not be able to cause the build to fail. This is because there are a lot of issues it identified in the existing Python code. Hopefully we can gradually address those. If so, we can eventually have pylint require minimum code quality, or else fail the build.
After adding pylint, it identified several fatal errors in the existing tests. This PR corrects those as well. None of them are tricky or risky changes.
